banshee8787 Posted November 14, 2003 Report Share Posted November 14, 2003 Hey guys, I have a 2003 banshee that I just conpletely rebuilt and modified but i can't keep it running. one day its running mint the next it doesn't start. It has a cool head, stage 3 port and polish, bored carbs, carbon fiber reeds, prodesign intake, sst pipes. What do you think the jetting should be? The temp is about 45 degrees at like 1000 feet above sea level. I have a 320 mains, 12.5 pilot, and I am on the 1st setting for the needle jet. I have rebuilt and cleaned the carbs a bunch of times. What do you think it is or atleast what should the settings be? PLease help Quote Link to comment Share on other sites More sharing options...
bansheeman8 Posted November 14, 2003 Report Share Posted November 14, 2003 what kinda carb are you running cuz if its the stock carb then a 12.5 pilot is way too small. Stock is a 25 if Im correct. Quote Link to comment Share on other sites More sharing options...
banshee8787 Posted November 14, 2003 Author Report Share Posted November 14, 2003 yea im running stock carbs and im pretty sure the jets are stock becasue they came right from the factory. Just a general question. Can plugs be fouled if there is still spark? Cause im wondering if there not firing while inside the cylinder. I also have a feeling that my main jetts are to big. and does anyone know how to contact FMF directly for jetting advice. I would really appreciate any advice thanks banshee8787 Quote Link to comment Share on other sites More sharing options...
mrmatt Posted November 14, 2003 Report Share Posted November 14, 2003 You'll get better jetting advice on here, than you would by calling FMF. This isn't really posted in the right spot, but I'm sure one of the experts will see this and respond. IMHO the stock pilot jets (25) might be a little small and would make it hard to start, but they shouldn't keep it from starting. The 320 mains are probably close, but they won't really affect how it starts. I would check and make sure that you're TORS isn't acting up. Mine went out in less than a year. The quick way to eliminate this possibility is to unplug the three wire connector that goes to the control box. The control box is mounted under the gas tank on the left side of the frame. Of course, there are always the usually reasons why it won't start: Gas tank empty, petcock turned off, choke tube missing, carb slides in backwards, rag in intake...... One of these is usually why mine won't start. Quote Link to comment Share on other sites More sharing options...
